In-toeing in children with cerebral palsy can lead to functional difficulties during gait. This may require surgical management to restore a normal foot progression angle. For this reason it is important to indentify the presence of internal rotation and to establish where the abnormal rotation is occurring. This can be done relatively easily in otherwise healthy subjects by examining foot progression angle as the subject walks towards the assessor. In cerebral palsy the often severely affected gait pattern and potential asymmetry at the pelvis means that in-toeing may be more difficult to identify. Gait laboratory data of 245 subjects with cerebral palsy were studied retrospectively. Of these 102 (41.63%) demonstrated in-toeing relative to the pelvis of one or both limbs. Eleven diplegic subjects (16.18%) in-toed bilaterally giving a total of 113 in-toeing limbs for analysis. Of those, 17 (50%) hemiplegic limbs and 20 (25.32%) diplegic limbs demonstrated a foot progression angle within normal limits due to compensations at the pelvis.
脑瘫患儿的内八字步态会导致行走时出现功能障碍。这可能需要手术治疗来恢复正常的足前进角。因此，识别内旋的存在并确定异常旋转发生的部位非常重要。在其他方面健康的受试者中，当受试者朝着评估者行走时，通过检查足前进角，相对容易做到这一点。在脑瘫患者中，通常严重受影响的步态模式和骨盆潜在的不对称意味着内八字步态可能更难识别。对245例脑瘫患者的步态实验室数据进行了回顾性研究。其中102例（41.63%）表现出相对于一侧或双侧骨盆的内八字步态。11例双侧瘫患者（16.18%）双侧内八字步态，共有113条内八字步态肢体用于分析。其中，17条偏瘫肢体（50%）和20条双侧瘫肢体（25.32%）由于骨盆的代偿作用，足前进角在正常范围内。
